Video not working in Instagram with Opera Developer under Linux Mint 17 x86_64.

Hello everyone!
I'm using Opera Developer under Linux Mint 17 x86_64. So likely this's pepperflash problem. Browser works really good on few years old notebook. Smooth scrolling, nice responsiveness. Pepperflash nonfree plugin for my distro works good on youtube.com, vk.com and some other resources. But I have no chance to watch videos in instagramm. I see preview image and playback button but when I push it nothing happens. Also, when I put mouse on playback button I see in the left bottom corner "javascript:;".
I've seen some ppl resolve similar problem(no video from instagram/vine) in chromium web-browser by disabling hardware acceleration in chrome://flags or smth like that. So, I've found hardware acceleration flag in opera preferences, also I've investigated additional flags/features in opera://flags, opera://plugins. Nothing helped, so I still need to copy+paste link to another browser to watch some videos.

Sorry for my bad English, I hope this information will help to improve opera. If you need some additional information please let me know, I'll post more details.

I have yet to see a single video work from anywhere under Version:25.0.1614.18 - System: Ubuntu 14.04.1 LTS (x86_64; KDE.

I have compiled and installed the latest ffmpeg version 2.4.1 Copyright (c) 2000-2014 the FFmpeg developers
built on Sep 24 2014 09:57:08 with gcc 4.8 (Ubuntu 4.8.2-19ubuntu1) and still no video support.

anika200, read my post. For Opera Developer on linux you need to install additional plugin. For linux mint you should install pepperflash. You can read here how to do that on Linux mint.

PS: for other platforms you may need to install another packager, for instance, on gentoo you need to install chromium-plugins-bin package. I think you can easily google proper package for your platform.

JUst tried to install multiple packages regarding ffmpeg, libavc, x264 etc. Still no effect for mentioned web-resource. I can play only youtube and some other videos. At the same time, video in firefox can be played from any resource. Still need your help:(

seshn, sorry I was not clear. I can play videos on youtube etc through pepperflash but not anything that needs ffmpeg or x264 even after compiling and installing ffmpeg.

Yes, but look at the version of ffmpeg I mentioned above, compared to the version you compiled and installed. According to the link I posted above, it does not work with the newer versions of ffmpeg and the blog posts are wrong.

In Linux Mint, Opera take the libpepflashplayer.so from /opt/google/chrome/PepperFlash. Try installing pepperflashplugin-nonfree doing sudo apt-get install pepperflashplugin-nonfree. It installs on /usr/lib/pepperflashplugin-nonfree. Then take the newly-installed libpepflashplayer.so and replace the Chrome one.
